Definitions
- the present invention relates to a device and method for treating drinking water to produce water for topical detergent, cosmetic and/or therapeutic use.
- Drinking water is water which, drawn from various sources and appropriately treated, is suitable for human consumption, is mainly supplied by water mains (i.e. facilities and equipments for water intake, piping and distribution), and, to be classified "drinkable" and distributed to users, must conform with strict legal requirements.
- drinking water normally has a substantially neutral pH, is relatively hard (i.e. relatively rich in so-called “scaling” salts, in particular calcium bicarbonate and magnesium), and has a relatively high chlorine content (added as a disinfectant).
- scaling salts, in particular calcium bicarbonate and magnesium
- drinking water is not altogether satisfactory when used, together with (surface-active) detergents, for simply cleansing human skin, and even less so when used for cosmetic or therapeutic treatment.
- the pH of human skin is acid, whereas that of drinking water is substantially neutral, so that drinking water has an aggressive effect on the skin when applied even simply for washing or rinsing purposes.
- the pH of the skin is known to be altered, and is normally more basic than that of healthy skin.
- the skin of subjects suffering from atopic dermatitis substitutional eczema
- the skin of subjects suffering from atopic dermatitis has a more basic pH than that of normal subjects, both in the skin areas affected by the eczema, and, to a lesser but still significant degree, in the apparently healthy skin areas.
- Any type of dermatological treatment may call for rinsing the skin afterwards, and, precisely on account of the above characteristics, rinsing the skin with drinking water may possibly impair any benefits derived from the treatment.
- a device and method for treating drinking water to produce water for topical detergent, cosmetic and/or therapeutic use as claimed in the accompanying Claims 1 and 10 respectively.
- Number 1 in the accompanying drawing indicates as a whole a device for treating drinking water to produce water for topical detergent, cosmetic and/or therapeutic use.
- Device 1 comprises a casing 2 housing a hydraulic circuit 3, along which flows a water stream, indicated by arrow 4 in the drawing, and which has an inlet 5 and an outlet 6 located at opposite ends of casing 2.
- Inlet 5 has connecting means 7 for connection to a drinking water mains 8; connecting means 7 comprise, for example, a hose 9 fitted on its free end with a fitting 10 connectable in any known manner to an end fixture 11 of mains 8; and end fixture 11 may conveniently be a tap of an existing sanitary fixture (bathtub or basin), or a tap installed specifically for use with device 1.
- connecting means 7 comprise a branch pipe 12 from mains 8, and a tap 13 or other suitable control member for feeding water stream 4 into circuit 3.
- Outlet 6 is also provided with an optional tap 14.
- Device 1 comprises treating means 15 for altering the chemical-physical properties of water stream 4 flowing in circuit 3.
- Treating means 15 comprise a number of treating units 16 arranged in series along circuit 3 to intercept water stream 4.
- units 16 comprise respective replaceable cartridges 17 inserted removably inside respective seats 18 in casing 2, and arranged in series along circuit 3 to intercept water stream 4.
- Each unit 16, i.e. each cartridge 17, provides for a specific treatment of water stream 4.
- a first unit 16a has water softening means 21.
- unit 16a comprises a softening cartridge 17a housed in a seat 18a, and having a dispenser 22 (of any known type and only shown schematically in the drawing) for dispensing substances by which to precipitate calcium and other salts dissolved in the water, and a precipitate filter 23.
- Calcium may be removed or reduced, for example, using known chemical precipitation systems employing lime, sodium carbonate or cation exchange resins.
- a second unit 16b is a chlorine-removal unit comprising a chlorine-removal cartridge 17b housed in a seat 18b.
- Chlorine may be removed using any known system, such as known polycarbonate lines.
- a third unit 16c has pH-adjusting means 27 for imparting an acid pH to water stream 4, and specifically a pH ranging between approximately 3.0 and 6.0, and preferably of about 5.5.
- unit 16c comprises a pH-regulating cartridge 17c housed in a seat 18c, and having a known dispenser 28 (shown only schematically in the drawing) for releasing into water stream 4 an acid substance by which to form a buffer system.
- buffer systems are citric/citrate acid; carbonic/bicarbonate acid; lactic/lactate acid.
- a number of pH-regulating cartridges 17c are provided, which can be inserted selectively inside seat 18c, and each of which provides for producing a predetermined pH value of water stream 4.
- a fourth unit 16d is an enriching unit, which comprises an enriching cartridge 17d housed in a seat 18d, and having a known dispenser 29 for releasing into water stream 4 one or more substances selected according to the specific cosmetic or therapeutic treatment to be performed.
- a number of enriching cartridges 17d are provided, which can be inserted selectively inside seat 18d, and each of which provides for releasing one or more substances for treating a specific pathology or disorder.
- water stream 4 is circulated in device 1 by the operating pressure of mains 8, though device 1 may comprise circulating means of its own, e.g. a known pump (not shown) for circulating water between inlet 5 and outlet 6.
- a known pump not shown
- circuit 3 The order in which units 16 are arranged along circuit 3 may, obviously, be other than as shown purely by way of example.
- Device 1 implementing the method according to the invention operates as follows.
- Device 1 alters the chemical-physical properties of water stream 4. More specifically, a water-softening step is performed in unit 16a; a chlorine-removal step is performed in unit 16b; a pH-adjusting step is performed in unit 16c, in which the pH of water stream 4 is brought to an acid pH as described above and of a specific value depending on the selected pH-regulating cartridge 17c; and an enriching step is performed in unit 16d, in which water stream 4 is enriched with one or more substances released by cartridge 17d.
- the above steps may be performed in other than the order described, depending on the arrangement of respective units 16 along circuit 3. Some or all of the steps indicated may be performed simultaneously. For which purpose, provision may be made, for example, for an integrated unit incorporating the functions of a number of units 16, i.e. a multifunction cartridge which, inserted inside a seat 18, performs a number of different functions; or a number of cartridges 17 may be housed in the same seat 18, in which the respective functions are performed simultaneously.
- the treated water issuing from outlet 6 can be applied directly to the human skin for detergent, cosmetic and therapeutic purposes, and for preventing skin disorders, flaws and pathologies.
- water can therefore be produced cheaply and easily for effective use as a straightforward skin cleanser, for cosmetic and therapeutic treatment, and for preventing the onset of skin pathologies.
- the device and method according to the invention enable this to be done using ordinary drinking water (which is obviously available cheaply to any user connected to a public water mains) by eliminating the aforementioned drawbacks typically associated with untreated drinking water.
- the water prepared according to the invention in fact, has a pH similar to that of human skin, so does not even temporarily affect the pH of the skin, and in fact even enhances its buffer capacity; is relatively soft, and therefore provides for effective cleansing with a small amount of surface-active detergent; and contains substantially no chlorine or other aggressive agents.
- the water produced according to the invention greatly reduces the aggressive action on the skin of normal drinking water.
- the water treated in accordance with the invention is therefore ideal for rinsing the skin after any type of dermatological (cleansing, cosmetic or therapeutic) treatment, and in no way impairs the benefits derived from the treatment.
- the device according to the invention is cheap and easy to produce, install and operate, and is designed for both domestic and professional use (beauty centres, hospitals, clinics, etc.).
- the water prepared using the device and method according to the invention safeguards the skin against harm of any sort, and, if used regularly, provides for effectively preventing the onset of various skin disorders or pathologies, or even straightforward skin defects.
- the water prepared using the device and method according to the invention has proved particularly effective in treating all pathologies and disorders involving abnormal pH of the skin, such as atopic dermatitis (constitutional eczema) and contagious dermatitis (topical eczema).
- the device according to the invention provides for targeting water treatment by selecting the appropriate cartridges from those available: in particular, water can be produced with a specific pH value selected according to the condition of the subject for treatment; and substances beneficial to a specific disorder can be added to the water.
